The Best | The Largest Manufacturer | The Highest Quality | Market Leader | The Biggest | The Widest Range in Borneo (Sabah, Sarawak, Brunei)

 

🏭 Product Description

The Square Internal Rubber Cap from RUBASIA RUBBERTECH INDUSTRIES is a precision-engineered protective insert designed to fit inside square-shaped metal or plastic tubing.
It is widely used on chairs, tables, racks, benches, and industrial frames to seal, protect, and stabilize the structure.

Our rubber caps are manufactured using high-quality synthetic rubber compounds (EPDM, NBR, or Natural Rubber) for superior elasticity, shock absorption, and resistance to wear, weather, and impact.

Available Sizes:

• 12 × 12 mm
• 16 × 16 mm
• 19 × 19 mm
• 22 × 22 mm
• 25 × 25 mm
• 32 × 32 mm
• 38 × 38 mm
• 51 × 51 mm

 

⚙️ Ultra-Detailed Product Features

🧩 1. Internal Fit Precision Design

• Specifically engineered to fit inside square tubing, creating a clean, flush finish with no exposed edges.
• The tapered wall structure allows for progressive compression, ensuring tight frictional grip within the tubing.
• Chamfered edges guide smooth insertion and protect the tube mouth from deformation.

Benefit: Provides a professional, concealed appearance with maximum mechanical retention — even under continuous load or vibration.

 

🧱 2. High-Grade Synthetic Rubber Compound

• Made from premium EPDM/NBR blend, balancing flexibility and strength.
• Maintains elasticity across extreme temperature ranges (-40 °C to +120 °C).
• Resistant to ozone, UV, humidity, oils, mild acids, and cleaning agents — perfect for Borneo’s humid tropical climate.

Benefit: Ensures long-term durability and stability for both indoor and outdoor installations in Sabah, Sarawak, and Brunei.

 

🔇 3. Noise Reduction Technology

• The dense rubber material absorbs vibration and eliminates noise when furniture moves.
• Prevents the metallic scraping sounds that commonly occur with steel or aluminum frames.

Benefit: Ideal for schools, offices, hospitals, hotels, and restaurants where quiet environments are important.

 

🛡️ 4. Superior Floor Protection Layer

• The rubber base acts as a soft, non-marking barrier between the furniture and floor surface.
• Prevents scratches, dents, or stains on hardwood, ceramic, vinyl, or marble flooring.
• The anti-slip friction texture maintains stable contact even on polished tiles or epoxy-coated surfaces.

Benefit: Extends floor life and maintains a clean, professional appearance.

 

💨 5. Sealing & Contaminant Protection

• The internal plug seals off the open tubing, preventing the entry of water, dust, rust, insects, or debris.
• Protects internal tube walls from corrosion and moisture build-up, especially in outdoor applications.

Benefit: Maintains furniture integrity and hygiene — essential for healthcare, laboratory, and food processing sectors.

 

⚡ 6. Impact & Vibration Absorption

• The cap body absorbs shocks from machine movement, heavy loads, or equipment vibration.
• Reduces fatigue stress on welded joints or fasteners.

Benefit: Extends service life of furniture and mechanical frames — trusted by industrial users in Bintulu, Miri, and Sandakan.

 

🧰 7. Ease of Installation

• Push-fit or light tap installation — no glue, screws, or special tools required.
• For tight fits, soaking in warm water softens the rubber, improving flexibility.
• Can be removed or replaced easily for cleaning or maintenance.

Benefit: Saves installation time for OEM furniture manufacturers and contractors across Borneo.

 

🌦️ 8. Weather & UV Resistance

• Formulated to withstand prolonged sun exposure, tropical rainfall, and humidity without cracking.
• Remains flexible and non-brittle under outdoor café, patio, or coastal environments (e.g. Kudat, Labuan, Miri, Tutong).

Benefit: Provides reliable, long-term protection in indoor and outdoor conditions.

 

🧱 9. Aesthetic & Finishing Enhancement

• Smooth black finish enhances the visual quality of furniture and metal frameworks.
• Eliminates sharp metal edges, ensuring user safety.
• Complements modern furniture design aesthetics.

Benefit: Perfect finishing accessory for export-grade furniture produced in Sabah and Sarawak.

 

🪨 10. Structural Reinforcement

• Adds compressive stability to tube ends, reducing deformation under vertical loads.
• Distributes weight evenly across the floor contact area.

Benefit: Strengthens the structural integrity of frames used in industrial racks, gym equipment, and medical trolleys.
